Functional Outcome of Uncemented (Hydroxyapatite Coated) Bipolar Hemiarthroplasty in Fracture Neck of Femur in Elderly.

BACKGROUND

Femoral neck fractures in the elderly are associated with high morbidity and reduced mobility. Uncemented hydroxyapatite-coated bipolar hemiarthroplasty is increasingly used to avoid cement-related complications. This study evaluated postoperative functional outcomes using the Harris Hip Score (HHS).

METHODS

A prospective observational study was conducted on 38 elderly patients (≥65 years) with displaced intracapsular femoral neck fractures who underwent uncemented hydroxyapatite-coated bipolar hemiarthroplasty. Functional outcome was assessed using the Harris Hip Score at nine months. Descriptive statistics (mean ± SD) were used.

RESULTS

The mean Harris Hip Score at nine months was 88.4 ± 9.2. Outcomes were classified as excellent in 25 patients (66%), good in 7 (18%), fair in 4 (10%), and poor in 2 (5%). Most patients regained independent ambulation with minimal complications.

CONCLUSIONS

Uncemented hydroxyapatite-coated bipolar hemiarthroplasty provides satisfactory early functional outcomes in elderly patients with femoral neck fractures, with high HHS scores and low complication rates over nine months.
